When you add water to clay you will notice more swelling than you will when adding water to sandstone. This is due to clay being more permeable than sandstone. This allows clay to absorb and retain water at a quicker rate.
due to ion exchange and change in salinity.
..
No. Shale forms from clay and silt, which are much finer than the sand that forms sandstone.
Granite is more expensive as it is made under the earth (metamorphic rock) and harder to extract than sandstone which is a sedimentary rock
Sandy soils are much more permeable that clay soils.
No way
chalk is weaker than clay because of the particles which are migrated inside it. Chalk can float while clay will sink. Clay can also absorb muhc more water No, Clay is stronger than chalk. OF COURSE CHALK IS STRONGER THAN CLAY, HONEY!!! IT IS HARDER AND ABSORBS LESS WATER. Sweetie, why du think clay sinks?

No. Sandstone is usually weaker than quartzite.
Sandstone is more easily eroded than lava.
Clay is not more porous than sand. Porous means permeable by fluids, so, sand is more porous than clay.

Because shale and sandstone don't let water pass them, but conglomerate does
In quartzite the grains are essentially welded together under pressure, which holds them together much more strongly than the fairly weak cementation in sandstone.
Siltstone is a sedimentary rock. It forms on river beds when silt compressed together.
Not a whole lot of difference, other than the size of the particles and possibly the cementing material.
sandstone is not harder than flint because sandstone breaks in to smaller pieces.
dry does not weigh more than wet mud by vani
The weight of a sandstone statue will depend on the size of the statue. Larger statues will weigh more than smaller statues. Sandstone generally weighs 150 pounds per cubic foot.
